I want to install free vpn under my kubuntu 22.04
From the site I uploaded a file vpnbook-openvpn-us1.zip and unpacking it I got 4 files :
vpnbook-us1-tcp443.ovpn
vpnbook-us1-tcp80.ovpn
vpnbook-us1-udp25000.ovpn
vpnbook-us1-udp53.ovpn
I tried to run command but got error :
sudo vpnbook vpnbook-us1-tcp443.ovpn
[sudo] password for master:
sudo: vpnbook: command not found
I did not find "vpnbook" comand in my OS or under synaptic. I find some youtube video manual...
Where from have I to get vpnbook command to install free vpn?
